■Ingress filtering only affects tagged frames.
■If ingress filtering is disabled, the interface accepts any
■If ingress filtering is enabled, the interface discards incoming frames tagged for VLANs that do not include the ingress port in their member set.
■Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or STP. However, they do affect VLAN dependent BPDU frames, such as GMRP.
■GVRP – The configured state of GVRP for the interface. GVRP must be globally enabled for the switch before this setting can take effect (page
■GARP Join Timer – The interval (between 20 and 1000 centiseconds) between transmitting requests/queries to participate in a VLAN group. The default is 20 centiseconds.
■GARP Leave Timer – The interval (between 60 and 3000 centiseconds) a port waits before leaving a VLAN group. Set this time to more than twice the join time. This ensures that after a Leave or LeaveAll message has been issued, the applicants can rejoin before the port actually leaves the group. The default is 60 centiseconds.
■GARP LeaveAll Timer – The interval (between 500 and 18,000 centiseconds) between sending out a LeaveAll query message for VLAN group participants and the port leaving the group. This interval should be considerably larger than the Leave Time to minimize the amount of traffic generated by nodes rejoining the group. The default is 1000 centiseconds.
■VLANs on Selected Port – The port is statically assigned to the specified VLAN.
■Membership Type – The port’s static VLAN membership type.
■Tagged: The interface is a member of the VLAN. All packets transmitted by the port on this VLAN are tagged, that is, carry a tag and therefore carry VLAN or COS information.
■Untagged: The interface is a member of the VLAN. All packets transmitted by the port on this VLAN are untagged, that is, do not carry a tag and therefore do not carry VLAN or COS information.
■Forbidden: The interface is forbidden from automatically joining the VLAN through GVRP. See “Automatic VLAN Registration” on page
■Remove: The selected interface is removed from the VLAN.
